Abstract
The invention provides a negative pressure drainage bottle for closed drainage of pleural cavity. The drainage bottle comprises a single bottle with double cavities, wherein the lower cavity with a larger cross section is a negative pressure liquid cavity, while the upper cavity with a smaller cross section is a drainage liquid cavity; a negative pressure pipe is connected between the drainage liquid cavity and the negative pressure liquid cavity; one end of the negative pressure pipe extends into the negative pressure liquid cavity, while the other end of the negative pressure pipe is connected with the upper part of the drainage liquid cavity; a liquid charging pipe is arranged in the negative pressure liquid cavity, and the liquid charging pipe and the negative pressure pipe are combined into a whole but not communicated with each other; a liquid feed hole is formed on the liquid charging pipe; and a drainage pipe joint is formed on the upper part of the drainage liquid cavity. According to the negative pressure drainage bottle, the pipe is prevented from being connected by mistake when the drainage bottle is used, the poor closing phenomenon can be possibly reduced, a negative pressure liquid column can be seen, and the drainage is convenient in carrying and prevented from falling because the cross section of the lower cavity is larger than that of the of upper cavity. The whole device is stable, and has the advantages of strong sealing property, convenience in pipe connection, simpleness in use, safety and high efficiency.
Description
Technical field
The present invention relates to a kind of Novel negative-pressure drainage bottle, particularly relate to a kind of closed drainage of pleural cavity negative pressure drainage vessel.
Background technology
The closed thoracic drainage bottle that current clinical treatment generally uses is two bottle Loosely coupled and forms, so all there is following shortcoming: (1) each bottle has two respective connectors, have four connections, add that each bottle has bottle cap again mostly, always have six connecting portions, very easily make mistakes during use, be also unfavorable for sealing.(2) cross section of negative pressure liquid bottle is too little, if liquid adds very little, when fluid column rises with negative pressure, negative tube lower surface is easily exposed and on liquid level, sucked air enter thoracic cavity, if liquid adds too much, is unfavorable for again the extraction of gas in thoracic cavity, liquid.(3) filling opening also often upward, easy contaminated negative pressure liquid bottle.(4) two bottles of cross sections are little, place unstable (have establish in bottom several rectangular, open during use, but also easily come off, use also inconvenient), there is no handheld devices, be unfavorable for guiding and supporting action.In order to thoroughly solve above-mentioned Railway Project, Te Famingben Novel negative-pressure drainage bottle.
Summary of the invention
The object of the present invention is to provide a kind of closed drainage of pleural cavity negative pressure drainage vessel, solve that the closed drainage bottle sealability used clinically is at present poor, error-prone adapter, bad, the easy pollution of drainage effect, shelf-stability are poor, guide and support the problems such as inconvenient.
The present invention realizes like this, it comprises drain sap cavity, negative pressure sap cavity, negative tube, drainage tube interface, filling opening, liquid-feeding tube, it is characterized in that being made up of single bottle of two-chamber, cavity of resorption cross section is negative pressure sap cavity more greatly, epicoele cross section is less is drain sap cavity, negative tube is connected with between drain sap cavity and negative pressure sap cavity, negative pressure sap cavity is stretched in one end of negative tube, the other end of negative tube connects the upper lateral part of drain sap cavity, negative pressure sap cavity is provided with a liquid-feeding tube, liquid-feeding tube and negative tube do in aggregates and do not communicate, liquid-feeding tube is provided with a liquid filling hole, one drainage tube interface is arranged at drain sap cavity top.
Technique effect of the present invention is: liquid filling hole is located at liquid-feeding tube sidewall, is not easily entered by dirt; Negative tube is directly communicated with negative pressure sap cavity and drain sap cavity, and whole device only has a connector, and when avoiding using, pipe connection makes mistakes and reduces airtight bad phenomenon as far as possible, and can see negative pressure fluid column, and is convenient to guide and support; Cavity of resorption is larger than epicoele cross section, not easily topples over; Whole device good airproof performance, only have the adapter of interface and can not cause adapter mistake, drainage effect splendid, not easily contaminated, place and stablize, be convenient to guide and support, use simple, safety, efficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In the drawings, 1, drain sap cavity 2, negative pressure sap cavity 3, negative tube 4, drainage tube interface 5, filling opening 6, liquid-feeding tube 7, confining liquid (normal saline) 8, drain.
Detailed description of the invention
As shown in Figure 1, the present invention realizes like this, be made up of single bottle of two-chamber, cavity of resorption cross section is negative pressure sap cavity 2 more greatly, and epicoele cross section is less is drain sap cavity 1, is connected with negative tube 3 between upper and lower cavity, negative pressure sap cavity is provided with a liquid-feeding tube 6, liquid-feeding tube 6 does in aggregates with negative tube 3 and does not communicate, and is provided with a liquid filling hole 5, and a drainage tube interface 4 is arranged at drain sap cavity 1 top.Effect is: liquid filling hole 5 is located at liquid-feeding tube 6 sidewall, is not easily entered by dirt; Negative tube 3 is directly communicated with negative pressure sap cavity 2 and drain sap cavity 1, and when avoiding using, pipe connection makes mistakes and reduces airtight bad phenomenon as far as possible, and can see negative pressure fluid column, and is convenient to guide and support; Cavity of resorption is larger than epicoele cross section, not easily topples over.Add confining liquid (normal saline) 7 from liquid filling hole 5 during use then can to exceeding more than negative tube lower surface about 0.8-1.2cm, carry out after breast wears, be connected with connection tube 4 by pipe, draw chest drainage thing 8, along with the extraction of gas-liquid in thoracic cavity, stop when normal saline rises to pressure and intrathoracic pressure dynamic balance in pipe along negative tube 3 and change with intrathoracic pressure power and beat up and down, even if fluid column is higher, because negative pressure sap cavity cross section is large, fall under liquid level in container obviously, negative tube lower end can not be caused to expose the danger of liquid level.Whole device good airproof performance, only have the adapter of interface and can not cause adapter mistake, drainage effect splendid, not easily contaminated, place and stablize, be convenient to guide and support, use simple, safety, efficient.
